Description

Functions for debugging. If you left these functions in your code then a warning is generated to remind you about left usages. Also some functions (and data types) are convenient for prototyping.

Synopsis

trace :: String -> a -> a
traceM :: Applicative f => String -> f ()
traceId :: String -> String
traceShow :: Show a => a -> b -> b
traceShowId :: Show a => a -> a
traceShowM :: (Show a, Applicative f) => a -> f ()
error :: forall (r :: RuntimeRep). forall (a :: TYPE r). HasCallStack => Text -> a
data Undefined = Undefined
undefined :: forall (r :: RuntimeRep). forall (a :: TYPE r). HasCallStack => a

Tracing

trace :: String -> a -> a #

Warning: trace remains in code

Version of trace that leaves warning.

traceM :: Applicative f => String -> f () #

Warning: traceM remains in code

Version of traceM that leaves warning.

traceId :: String -> String #

Warning: traceId remains in code

Version of traceId that leaves warning.

traceShow :: Show a => a -> b -> b #

Warning: traceShow remains in code

Version of traceShow that leaves warning.

traceShowId :: Show a => a -> a #

Warning: traceShowId remains in code

traceShowM :: (Show a, Applicative f) => a -> f () #

Warning: traceShowM remains in code

Version of traceShowM that leaves warning.

Imprecise error

error :: forall (r :: RuntimeRep). forall (a :: TYPE r). HasCallStack => Text -> a #

error that takes Text as an argument.

data Undefined #

Warning: Undefined type remains in code

Similar to undefined but data type.
